International Journal of Hydromechatronics (IJHM)

Forthcoming articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

Forthcoming articles must be purchased for the purposes of research, teaching and private study only. These articles can be cited using the expression "in press". For example: Smith, J. (in press). Article Title. Journal Title.

  • Wear monitoring of hydraulic reciprocating seal based on contact stress   Order a copy of this article
    by Xiuxu Zhao, Jiaping Duan, Haile Tang, Appiah Emmanuel 
    Abstract: Timely and accurate monitoring of seal wear is crucial for ensuring the safe and efficient operation of hydraulic cylinders during actual operation. This study designed a fibre Bragg grating (FBG) sensor monitoring unit to achieve hydraulic cylinder seal wear monitoring based on sealing surface contact stress. Experimental research was conducted using a specially designed monitoring experimental system, and the results showed that as the wear of the piston rod seal increased, the circumferential and axial contact stresses of the seal first increased and then decreased. This study provides an effective means for further investigating the wear and performance degradation process of hydraulic reciprocating seals under actual usage conditions.
    Keywords: hydraulic reciprocating seal; contact stress; wear monitoring; fibre grating sensor.

  • Numerical modelling and experimental study of fluid friction torque for clearance sealing of hydraulic rotary joints   Order a copy of this article
    by Xiuxu Zhao, Jing Zhang, Kyaw Thiha Soe, Jiantao Nie 
    Abstract: In high-speed hydraulic rotary joints, the frictional torque generated by the rotation of fluid in the sealing gap can affect the fluid delivery efficiency, increase the possibility of locking between the spindle and the fixed housing, and lead to the functional failure of the rotary joint. Therefore, it is of great significance to solve this problem through the reasonable design of the structural parameters of the rotary joint. This study first derived the calculation method for the friction torque of hydraulic rotary joints from a theoretical perspective, and then studied the relationship between the friction torque of hydraulic rotary joints and structural parameters (clearance value, effective sealing length, spindle diameter) through simulation and experiment. A corresponding mathematical model was established, and the effectiveness of the model was verified with actual rotary joint products, providing a theoretical basis for optimising the performance of high-speed hydraulic rotary joints.
    Keywords: high-speed hydraulic rotary joints; gap seal; friction torque; structural parameters.
